Vistar unveils the world's first Micro LED transparent watch with 65% transparency

There’s something quietly audacious about strapping a traditional mechanical watch to your wrist and having digital notifications float on top of it. That’s exactly what Vistar — Chenxian Photoelectric — is doing with its new Micro LED transparent watch, a device that tries to bridge the gap between analog craftsmanship and modern smart displays.

The watch combines a sub-2-inch TFT-based transparent Micro LED microdisplay with an ultra-thin glass substrate. Each Micro LED chip measures just 25μm — roughly a quarter the width of a human hair. The result is a watch face that achieves 65% light transmittance, meaning the mechanical hands and dial beneath remain clearly visible in standby or normal mode. Switch to smart mode, and notifications, time data, and other information appear to float in mid-air above the physical watch structure.

Peak brightness hits 3,000 nits, which puts it well beyond what even the brightest OLED smartwatches manage today. Vistar says the display remains readable under direct summer sunlight and at viewing angles up to 60 degrees — two conditions that typically wash out conventional transparent displays.

Micro LED has long been talked about as the eventual successor to OLED, offering better brightness, longer lifespan, and no burn-in risk. But manufacturing challenges — particularly around transferring millions of microscopic LEDs onto a substrate — have kept it mostly in the lab or in massive luxury TVs. Vistar’s transparent watch puts that technology on a wrist in a form factor that few have attempted.

The company hasn’t announced pricing or a release window yet. But the product itself is a reminder that the wearable industry isn’t just about squeezing faster processors into smaller cases — sometimes the interesting breakthroughs are in what the screen actually lets you see.
